1 ) What is the

length of the
shadow cast by

a 40 feet flag ▫ Height of the flag pole = 40 feet
pole at 2pm on ▫ Solar altitude = 54 degrees
21st March, ▫ Delhi (29N Lat, 77E Long). 2pm on 21st March

located in Delhi ▫ Sun tangent = tan ( solar altitude)
(29N Lat, 77E ▫ = tan ( 54 degrees )

Long). Solar ▫ = 1.37
altitude = 54 ▫ Length of the shadow = object height / sun tangent
degrees (Hint: ▫ = 40 feet / 1.37

you don’t need ▫ = 29.19 feet
to use any ▫ Length of the shadow is 29.19 feet

software. This
is just a simple
